Embroidering position setting device and method of operation thereof for an embroidering sewing machine

Abstract

An embroidering position setting device and method of operation thereof for an embroidering sewing machine are described. The embroidering sewing machine is capable of storing pattern data in a memory for a plurality of embroidery patterns which can be selectively read out to operate a stitch forming device to form the stitches of a selected pattern or patterns on a cloth to be stitched. An embroidering frame has a cloth extended thereon to be embroidered and is connected to an X-Y drive mechanism, said cloth having a mark located at an optional position for representing a reference embroidering position of the cloth. Jog keys are selectively operated to operate said X-Y drive mechanism thereby to shift said embroidering frame so that said reference embroidering position mark of the cloth may be located at the position under said machine needle in vertical alignment therewith. The position register key is operated to store said position of the reference embroidering position mark in an embroidering position memory as the reference embroidering position data. This position of the reference embroidering position mark is indicated together with crossed lines on a display which is operative in response to operation of said position register key. A pattern selecting device is then operated to select at least one of the embroidery patterns from said pattern memory, said selected embroidery pattern being stored in a memory (RAM) and being simultaneously indicated on said display with the center thereof being located at the center of said crossed lines.
